Chemists reveal the force within you

A new method for visualizing mechanical forces on the surface of a cell, reported in Nature Methods, provides the first detailed view of those forces, as they occur in real-time.

Protein plays role in helping plants see light

Plants do not have eyes or legs, yet they are able to "see" and move toward and away from light. This ability, called phototropism, is controlled by a series of molecular-level signals between proteins inside and between ...

Biochemical cell signals quantified for first time

Just as cell phones and computers transmit data through electronic networks, the cells of your body send and receive chemical messages through molecular pathways. The term "cell signaling" was coined more than 30 years ago ...

Controlling movements with light

German researchers at the Ruhr-Universitaet have succeeded in controlling the activity of certain nerve cells using light, thus influencing the movements of mice. By changing special receptors in nerve cells of the cerebellum ...

The forces of attraction: How cells change direction

Many cell types in higher organisms are capable of implementing directed motion in response to the presence of certain chemical attractants in their vicinity. A team led by Dr. Doris Heinrich of the Faculty of Physics and ...

Signaling pathway is 'executive software' of airway stem cells

Researchers at Duke University Medical Center have found out how mouse basal cells that line airways "decide" to become one of two types of cells that assist in airway-clearing duties. The findings could help provide new ...

Dynamics of crucial protein 'switch' revealed

Researchers at the University of Texas Medical Branch at Galveston and the University of California-San Diego School of Medicine have published a study that offers a new understanding of a protein critical to physiological ...
